Any chance these two locomotives will be released with DCC and sound in the future?
It is possible that they will do a Tsunami installed 4-6-0 with 63" drivers, as it is physically possible to fit a tsunami DSD in the tender, but it is impossible to equip a tsunami into the new 4-4-0s or the 4-6-0 with 52" drivers the tenders are first of all too short lengthwise and too short heightwise to fit the decoder and speaker.
Dear GN,
While I have no specifics, I am certain that the sound line will expand. I'll pass along your request.
Have fun!
